    Different weather makes people feel different．It influences health，intelligence and feelings．
    In August，it is very hot and wet in the south the US．People there have heart trouble and other kinds of health problems during this month．In the Northeast and the Middle West，it is very hot in the summer and very cold in the winter．People in these states have more heart trouble after the weather changes in February or March．
    The weather can also influence intelligence ． For example，in a 1983report by scientists，IQ(智商)of a group of students was very high when a very strong wind came, but after the strong wind,
    Their IQ was 10% lower than before. The wind can help people have higher intelligence. However,very hot weather can make it lower. Students in many schools of the US often get worse in exams(考试)in the hot months of the year(July and August).
    Weather also has a strong influence on people's feelings．Winter may be a bad time for thin people．They usually feel cold during these months．They might feel unhappy during cold weather．But fat people may have a hard time in hot summer．At about 18℃people become stronger．Low air pressure may make people forgetful．People leave more bags on buses and in shops on low-pressure days．
    Are you feeling sad，tired，forgetful，or unhappy today？It may be the weather's problem．

我在草堂中时，正值暮春，烟雨蒙蒙，园中游人熙攘。我细心观察，游人最少的地方，是杜诗碑林。___________________。但是，它仍不会吸引人们的注意，因为，产生于情感的诗，毕竟离铜臭太远。
①细心一想可以理解，在中国历史中，诗人是一种时尚。
②啊，他们并不为寻诗而来，像游鱼唼喋浮萍，他们需要的是这里春光的溪流，娱情的小径。
③再没有人愿意欣赏铿锵的音韵，更没有闲人来倾听诗人的诉求。
④尽管这诉求发自心灵，注满忧患，也不借助于语言暴力。
⑤而在当今，在利益追逐成为社会首选的今天，诗人早巳变成了社会中的边缘人物。

阅读下面的文段，完成后面题目。

   济南之所以有“泉城”之名，是由于城南有距今4.5亿年前的奥陶系石灰岩组成的千佛山地，这些石灰岩具有较多的熔洞或裂隙，在济南附近没（mò）入地下，并受到不透水的侵入岩岩体的①        （阻挡/阻止），而上覆的第四纪山前堆积物透水性不好，从而形成承压水构造。城南山区接受大气降水补给（jǐ），在城区则以上升泉形式涌出地表向外排出。金代有人立“名泉碑”，列举泉名七十有二，泉水众多，不可胜（shèng）数。历代诸家所论72泉亦不尽相同，②        （大致/大约）为趵突泉、黑虎泉、珍珠泉、五龙潭四大泉群。趵突泉又名瀑流，宋代开始称趵突泉。

   泉城四大泉群会流一处，在济南盆地最低处形成湖面46.5公顷的大明湖。北魏郦道元《水经注》③        （记载/记录），城西南有泺水，“北为大明湖”，后渐填埋堵塞，半为街市。金代起今城内湖沿袭大明湖之名。一湖烟水，绿树蔽空，妖娆多姿，风光秀美。清人刘凤浩咏湖有“四面荷花三面柳，□□□□□□□”，沿湖亭台楼阁，水树长廊，错落有致。其风貌不亚于“接天莲叶无穷碧，映日荷花别样红”的杭州西湖。
